NORFOLK, Va. (WAVY) — The Breezy Point Triathlon has been cancelled because of new security measures at Naval Station Norfolk following the shooting on the USS Mahan.

The Breezy Point Triathlon has been produced by the Tidewater Striders, a local running club, since 1992, and takes place at Naval Station Norfolk and in the adjacent Willoughby Bay. This year’s event was scheduled for Sunday, June 1 at 8 a.m., but the group announced Thursday afternoon it has been cancelled.

“Due to the shooting tragedy a few weeks ago, the base advised us on Monday that they are requiring background checks on every athlete, volunteer, guest, committee member, vendor, etc. We would need to collect the first, middle and last names, social security numbers and birth dates for all wishing to go through the gate,” said Brian Sagedy, a Tidewater Striders spokesman.

Sagedy said the group doesn’t believe that information can be gathered by the due date, May 23.

“We are receiving much resistance from athletes about providing social security numbers, and quite frankly, do not have the time nor the manpower to collect the information requested from athletes, guests, vendors, volunteers and anyone else associated with trying to access the base for the triathlon,” he said.

The running club will refund all entry fees. Sagedy said it will take about three weeks to process those refund checks.

The Tidewater Striders still plans to produce the triathlon in 2015. Since it’s inception, the event’s proceeds have been donated to a long list of local charities.
